Does callstats.io collect end-user feedback?

Yes, we do collect end-user feedback using our "sendUserFeedback" API. You can send a value between 1 to 5 for the overall conference quality, or for the audio/video. Additionally, you can also the end-user to wtite a comment. We categorize the 5 point score in to three categories:

Excellent (5)

Acceptable (4, 3)

Dissatisfactory (2, 1)

The reason is that the end-users are often unable to score correctly, and often the score between 2 to 4 are uncorrelated. Our observations lead to re-categorizing the points into three level score, which seems to work better.
